Title: Strainer
Inventor: FUKUSHIMA YASUO
IPC: B01D29/62
Filed: 1984-05-22
Abstract: PURPOSE:To treat a liquid material such as crude petroleum oil contg. solid foreign matters such as ice sludge without taking out the solid foreign matters out of the system by providing a vertical cylindrical filter chamber and a heating chamber below the filter chamber and melting the solid foreign matters to pass through a strainer. CONSTITUTION:When crude petroleum oil contg. sludge enters a filter chamber 1 from an inlet 11 for the liquid in the direction of an arrow mark and passes through a filter element 3, the sludge sticks together with other solid matters, if any, to the inside of the filter element 3, scraped off continuously by a scraping means 4, and falls in a heating chamber 2, where it is heated together with accompanying petroleum oil by a heating means 5 and melted to be transformed to the liquid state. The crude petroleum oil contg. the melted sludge rises up in the heating chamber 2 as the temp. rises, returns then to the filter chamber 1, passes through the filter element 3, and is discharged together with the crude petroleum oil supplied from a liquid inlet 11 through a liquid outlet 12. Unmelted solid matters settle to the bottom of the heating chamber, and are discharged from a drain port 21 when it is accumulated.

Title: Collagen-synthetic polymer matrix prepared by using multi-stage reaction
Inventor: UUNZA EMU RII
IPC: C07K17/08
Filed: 1995-04-27
Abstract: The present invention discloses collagen-synthetic polymer matrices which are prepared using a multiple step reaction. The first step of the reaction generally involves reacting collagen with a functionally activated synthetic hydrophilic polymer to form a collagen-synthetic polymer matrix. The synthetic hydrophilic polymer may be mono- or multifunctionally activated, but is preferably difunctionally activated, resulting in the formation of a crosslinked collagen matrix. The second step comprises modifying the collagen-synthetic polymer matrix according to one or more of the following methods: further crosslinking the matrix using a multifunctionally activated synthetic polymer, conjugating the matrix using a monofunctionally activated synthetic polymer, coupling biologically active molecules or glycosaminoglycans to the matrix, crosslinking the matrix using conventional chemical crosslinking agents, or modifying the collagen in the matrix by means of various chemical reactions. An optional third step may include further modification of the collagen-synthetic polymer matrix by covalently binding, for example, biologically active molecules or glycosaminoglycans to the matrix by means of available active groups on the synthetic hydrophilic polymers. Collagen-synthetic polymer matrices prepared according to the methods of the present invention have very low immunogenicity and can therefore be used to prepare biocompatible implants for use in a variety of medical applications. <IMAGE>

Filed: 1984-05-23
Abstract: PURPOSE:To recognize an image more clearly even if the revolution of a rotary body is relatively low, by forming a number of reflection surfaces for reflecting light in the same directions at a specific revolution position on the indication parts. CONSTITUTION:A wheel cover 1 has four character indication parts 2a-2d each of which consists of the characters ABC on the surface 1a. Each indication part 2a-2d is formed on the periphery in 90 deg., having the center O of revolution of a rotary body 1, and at the equal radius (r) position and in the equal posture state with respect to the center O of revolution. The cover 1 is made of the synthetic resin material colored into the color having low reflection factor, and reflection- surface work is applied only onto the prescribed parts of the indication parts 2a-2d. Therefore, when the revolution speed of the cover 1 becomes over a prescribed value, an operator can take the image ABC as if it stands still at a prescribed upper position of the rotary body 1 by the afterimage phenomenon of eyes.

Abstract: PURPOSE:To restore the titled device to a normal state only by the processing of a trouble by providing the device with a control means for rewinding rolled paper up to its initial position when a paper feeding detecting means detects the feeding of the rolled paper at the time of generating a trouble other than a paper feeding trouble. CONSTITUTION:When rolled paper 21a or 21b has been already fed at the time of generating a trouble other than paper jam, copying operation is released. A code number is assigned to each trouble other than the paper jam and the trouble is decided by the code number. Whether the rolled paper 21a or 21b has been already fed or not is decided in accordance with whether a sensor PS3 or PS4 is ON or not. A paper feeding port is checked,and when paper is fed from an upper paper feeding port, an upper paper feeding roll 22a is reversed and the rolled paper 21a is rewound until the sensor PS3 is turned off. Thus, the rolled paper 21a or 21b is automatically returned up to the initial set position and the device can be restored to the normal state only by the processing of the trouble.
